Design–Build cold storage made for Malaysia’s climate. We engineer walk-in chillers, freezers, and blast chillers using PU panels, quality refrigeration units, and smart temperature monitoring.

  • Types: Walk-in chiller (0–10°C), walk-in freezer (-10 to -25°C), blast chiller/shock freezer (-18 to -40°C)
  • Industries: F&B processing, cold-chain logistics, pharma/biotech, supermarkets & central kitchens
  • Coverage: Greater Klang Valley and nationwide on request
Engineering & Components
Built for performance, reliability, and hygiene. Our engineering covers the full coldroom envelope and refrigeration plant to deliver stable temperatures and low energy use.
  • PU Panels & Joints: 75–150 mm polyurethane panels, cam-lock joints, food-grade coated steel skins. Thermal breaks at junctions.
  • Floor System: High-density PIR/PU floor insulation with anti-slip stainless/chequer plate finish; heated thresholds for freezer doors.
  • Refrigeration Units: Branded hermetic/semi-hermetic compressors, air/water-cooled condensers, EC fans, correct refrigerant charge and superheat tuning.
  • Doors & Seals: Hinged or sliding, heated frames for sub-zero, magnetic gaskets, view windows, kick plates.
  • Defrost & Drainage: Electric/hot-gas defrost, insulated drain lines with heat trace, proper fall to trapped drains.
  • Monitoring & Alerts: Digital controllers, data logging, high/low temp alarms, remote WhatsApp/SMS alerts on request.
Key Components at a Glance
Performance & Guarantees
‘No Cold, No Pay’ — pay only when your room holds spec. We stand behind our builds with commissioning tests and warranty.
  • Scope: We design, install, and commission to your target temperature (e.g., 4°C chiller, -20°C freezer) at rated load.
  • Conditions: Proper power supply, door discipline, and rated product load. We verify insulation, airflow, and controls.
  • Commissioning: Leak test, evacuation, refrigerant charge, controller setup, and 24–48 hr temperature validation log.
  • Warranty: 45-day workmanship warranty from handover; extended service plans available.
Compliance & Hygiene
Food-safe construction and cleanability by design. Materials and details meet hygiene expectations for F&B and pharma.
  • Food-Grade Surfaces: Coated steel or stainless where required; silicone-free, food-safe sealants.
  • Condensation Control: Thermal breaks, heated frames, correct vapour barriers to prevent sweating.
  • Cleaning Access: Cove bases, flush details, removable drain pans, serviceable fan coils.
  • Local Compliance: Built to Malaysian codes and typical audit checklists for central kitchens and warehouses.

Selected Projects
Real-world builds delivering stable temperatures in Malaysia’s climate.
Maintenance & Aftercare
Protect performance and lifespan with planned service.
  • Intervals: Quarterly or semi-annual PM including coil cleaning, leak checks, drain maintenance, and controller calibration.
  • Spares: Stock of common parts (contactors, defrost heaters, gaskets, fans) to reduce downtime.
  • Response: Typical on-site response within 24–48 hours in Klang Valley; emergency call-out available.
Coldroom FAQs
Answers to common technical and delivery questions.

What power do I need?

Most systems require 3-phase power (415V) with dedicated breakers; small chillers may run on single-phase depending on load and size.

How big should the room be?

We size by product volume, turnover rate, target temperature, and door traffic. Provide internal L×W×H and we’ll calculate panel thickness and unit capacity.

How long is the timeline?

Typical lead time is 2–4 weeks for panels and equipment, plus 3–7 days for installation depending on room size and site readiness.
